Multiplication and division are opposite operations.

Since 3 × 5 = 15, 15 ÷ 3 = 5, and 15 ÷ 5 = 3.

Multiplication can be used to find a total when a given amount is added multiple times.
The amount Sandy bought is 3 times the amount Randy bought.
Randy bought 2 pounds. Solve for 3 groups of 2.

So, Sandy bought 6 pounds of chicken.

Avery broke each crayon into 2 pieces, so there are 2 times as many pieces as crayons.
Multiply 2 by 8 to find the number of crayon pieces.

The multiplication facts for 2 are shown below.

2 × 1 = 2
2 × 2 = 4
2 × 3 = 6
2 × 4 = 8
2 × 5 = 10
2 × 6 = 12
2 × 7 = 14
2 × 8 = 16
2 × 9 = 18
2 × 10 = 20
2 × 11 = 22
2 × 12 = 24

So, Avery has 16 crayon pieces.

Then, Avery divided the 16 pieces evenly between 4 cups.
Find the number of crayon pieces in each cup by dividing 16 by 4.

Use the relationship between multiplication and division to find the quotient.

4 × 4 = 16

So, there are 4 crayon pieces in each cup.
